Insert for stretch wrap roll core

ABSTRACT

An insert that inserts into a stretch wrap roll core having a first tubular body having a first and a second side, the first side having a first lip surrounding the first tubular body and a first curved handle within the inner side of the first side of the first tubular body, the second side of the first tubular body having a first attachment means for attaching to another tubular body, and a second tubular body having a first and a second side, the first side having a second lip surrounding the second tubular body and a second curved handle within the inner side of the first side of the second tubular body, the second side of the second tubular body having a second attachment means for attaching to the first tubular body&#39;s first attachment means.

BACKGROUND

The present invention is directed to an insert that is inserted within astretch wrap roll core.

In the stretch wrap industry, many attempts have been made to develop adevice that will allow users of a stretch wrap roll wrap film aroundgoods.

The most common method of wrapping goods in the industry is to insertones hands within the roll core and have the roll core spin around onesfingers while wrapping the goods. This method requires the user of thewrap roll core to wear gloves or suffer sever burning of the outer sidesof the fingers abutting the inner sides of the wrap roll core. Anotherdisadvantage with this method is that gloves used to prevent burningalso makes it difficult to insert the fingers within the wrap roll core.

Inserts have been developed to resolve the burning problem. Insert ringshave been developed to insert within the wrap roll core. The insertrings eliminate the friction between the fingers and the wrap roll core,for the friction is transferred to insert wrings. The only drawback tothe rings is that the fingers of the user are positioned in a mannerthat is contrary to how the hand normally rests. The fingers arelinearly lined and the inner fingers are placed so that they are furtherdepressed than the outer fingers. This is a very uncomfortable positionto hold something. A more natural position would be to have the outerfingers further depressed than the inner fingers.

Another insert that has been invented is an insert that has at least onehandle extend outward from the wrap roll core. This insert eliminatesthe burning associated with placing ones fingers within the roll core.The only disadvantage to this type of insert is that it makes it verydifficult to wrap things close to the ground.

An object of this invention is to provide an insert that will preventthe normal burning of the fingers when using a stretch wrap roll core.

Another object of the present invention is to provide an insert thatwill allow a user to insert the fingers in an ergonomic way.

A further object of the present invention is to provide an insert thatwill allow a user using a stretch wrap roll to wrap goods close to theground.

SUMMARY

The present invention is directed to an insert that is inserted within astretch wrap roll core that satisfies the following needs: providing auser with an ergonomic insert that inserts within the stretch wrap rollcore; prevents burning of the outer finger of the fingers insertedwithin the wrap roll core; and allows the user to wrap goods close tothe ground. The insert that inserts into a stretch wrap roll corecomprises a first tubular body having a first and a second side, thefirst side having a first lip surrounding the first tubular body and afirst curved handle within the inner side of the first side of the firsttubular body, the second side of the first tubular body having a firstattachment means for attaching to another tubular body, and a secondtubular body having a first and a second side, the first side having asecond lip surrounding the second tubular body and a second curvedhandle within the inner side of the first side of the second tubularbody, the second side of the second tubular body having a secondattachment means for attaching to the first tubular body's firstattachment means.

The present invention can be reusable or disposable. When the inventionis reusable, the first attachment means will be a male attachment meansand the second attachment means will be a female attachment means. Themale attachment means screws within the female attachment means so thatthe first and second curved handles are lined up linearly. In thedisposable model of the present invention, the first attachment meanswould be glued to the second attachment means so that the handles of thefirst and second tubular bodies are lined up linearly.

The present invention is used by inserting the first and second tubularbodies within a stretch wrap roll core. Then inserting ones fingerswithin the tubular bodies so that ones fingers ergonomically wrest onthe curved handles of the tubular bodies. Then placing the thumbs of thehands over the stretch wrap of the stretch wrap roll. Then tightlywrapping the stretch wrap around goods to be wrapped by using the thumbsto apply tension between the goods and the stretch wrap roll.

WRITTEN DESCRIPTION

As seen in FIGS. 1-9, an insert 100 that inserts into a stretch wraproll core 22 comprises a first tubular body 14 a having a first and asecond side, the first side having a first lip 18 surrounding the firsttubular body 14 a and a first curved handle 18 a within the inner sideof the first side of the first tubular body 14 a, the second side of thefirst tubular body 14 a having a first attachment means 12 for attachingto another tubular body, and a second tubular body 14 b having a firstand a second side, the first side having a second lip 18 surrounding thesecond tubular body 14 b and a second curved handle 18 a within theinner side of the first side of the second tubular body 14 b, the secondside of the second tubular body having a second attachment means 16 forattaching to the first tubular body's 14 a first attachment means 12.

In another embodiment of the present invention, the first attachmentmeans 12 is a male attachment means 12 and the second attachment means16 is a female attachment means 16. The male attachment means 12 screwswithin the female attachment means 16 after the first 12 and second 16attachment means are inserted within the stretch wrap roll core 22 a.

In a further embodiment of the present invention, the first 12 and thesecond 16 attachment means are permanently attached within the stretchwrap roll core 22.

The present invention can be reusable or disposable. When the inventionis reusable, the first attachment means 12 is a male attachment means 12and the second attachment means 16 is a female attachment means 16. Themale attachment means 12 screws within the second attachment means 16 sothat the first and second curved handles 18 a are lined up linearly. Inthe disposable model of the present invention, the first attachmentmeans 12 is glued to the second attachment means 16 so that the handlesof the first and second tubular bodies 18 a are lined up linearly.

As seen in FIGS. 10-13, the present invention is used by inserting theinsert's first and second tubular bodies 14 a-b within the stretch wraproll core 22. Then attaching the first tubular body's 14 a firstattachment means 12 to the second tubular body's 14 b second attachmentmeans 16 so that the handles of the first and second tubular bodies 18 aare lined up linearly. Then inserting ones fingers within the first andsecond tubular bodies 14 a-b so that ones fingers ergonomically wrest onthe curved handles of the tubular bodies 18 a. Then placing the thumbsof the hands over the stretch wrap of the stretch wrap roll. Thentightly wrapping the stretch wrap around goods to be wrapped by usingthe thumbs to apply tension between the goods and the stretch wrap roll.

An advantage of this invention is that it provides an insert thatprevents the normal burning of the fingers when using a stretch wraproll core.

Another advantage of the present invention is that it provides an insertthat allows a user to insert his fingers within the insert in anergonomic manner.

A further advantage of the present invention is that it provides aninsert that allows a user using a stretch wrap roll to wrap goods closeto the ground.
